Keywords: Fringe crop, photosensitive, pure line selection, hybridization, mutation breeding
Abstract: Pulses are the major sources of dietary protein in the vegetarian diet; they maintain soil fertility through biological nitrogen fixation. Besides, the pulse crops are very hardy and can sustain with residual moisture available in the dry areas. Hence the short duration pulses like cowpea and horse gram, constitue a major component in disaster management, particularly if there is a crop failure due to adverse climatic situations. Cowpea, horse gram, black gram, green gram and red gram are the important pulse crops traditionally grown in Kerala. Out of the area under pulses, more than 50 percent is contributed by Palakkad district. Almost all types of pulse crops including red gram are grown here. Cowpea is the most important pulse crop of Kerala. This accounts for about 75 percent of total area under pulses in the state. It is mainly grown as rotation crop in summer rice fallows, intercrop in coconut, tapioca, banana etc, fringe crop in rice fields also in homesteads. The crop is highly variable in terms of morphological characters. There are trailing, semi trailing and bushy varieties depending on their growth habit. Based on the consumption purpose there are grain type, vegetable type as well as dual purpose types. Diversity is also observed in many of their pod and grain characters. Pods may be longer than 35 cm as in case of Lola, a trailing vegetable type cowpea and smaller as 13 cm for Krishnamony (PTB-2). We can observe a multitude of grain colours viz, reddish brown, cream, light brown, black, mottled etc. Kanakamony (PTB-1) the first release cowpea variety from RARS, Pattambi is semi trailing and dual purpose with reddish brown grains, whereas Krishnmony is a bushy and vegetable type with black grains. Bhagyalakshmi on the other hand is a bushy and vegetable type having mottled grains. Horse gram is one of the hardies among the pulse crops. Two of our indigenous types Pattambi Local and Muthalamada Local are photosensitive varieties and suited to rabi seasons only. Varieties also differer in their grain colour as cream, reddish brown, brown etc. Though the State of rich in biodiversity of pulses, the area under the crops is showing a declinign pattern. Hence need of the hour is to conserve the existing biodivesity available within the crops and its utilization to enhance the productivity. Proper exploration studies in the traditional areaas are a pre requisite for collection and cataloguing of the biodiversity. The existing biodiversity of can be exploited by way of various crop improvement programmes. Direct introduction of minor pulse crops like horse gram, black gram, green gram etc. to non-traditional areas is an innovative method to popularise and conserve the diverstiy. Breeding techniques such as pure line selection, hybridization and mutation breeding can improve the characters of existing crops there by evolving photo insensitive horse gram varieties suited to all seasons, dual purpose cowpea varieties, bushy cowpea varieties with longer pods etc. We can employ these methods to utilize the existing diversity as well as create new variability, which in turn can enhance the farmer acceptance and yield.

Abstract: Drynaria quercifolia (L.) J. Smith (Polypodiaceae) has been widely used by ethnic groups of India to treat inflammation, rheumatism, headache, bone fracture, jaundice, etc. Herein, the anti-inflammatory, analgesic and anti-lipid peroxidative properties of the ethanolic extract of fertile fronds of Drynaria quercifolia (FF) was evaluated by standard ethnopharmacologica techniques. Oral administrations of FF produced significant inhibition of carrageenan-induced paw oedema, acetic acid induced vascular permeability, and HRBC membrane stability tests, almost comparable to that caused by indomethacin. FF significantly attenuated acute and delayed phases of formalin-induced pain and acetic acid-induced writing episodes in mice. The analgesia was comparable to that produced by sodium salicylate and aspirin respectively. Phytochemical analysis gave positive tests for catechin, coumarins, flavonoids, phenolics, saponin, steroids, and tannins. The total phenolics in FF was 96 mg/g. The results suggest the presence of potent anti-inflammetory and analgesic principles in DQ that justifies its use for alleviating painful inflammatory conditions.

Abstract: One of the most versatile and remumerative techniques for handling biodegradable solid wastes is composting. Apart for being a source of nitrogen, phosphorus, potassium, and other nutrients for plants, compost is also believed to suppress soil-borne diseases in plants. The various purposes for which compost is used include: agricultural residential, commercial purposes and municipal purposes. Also, it has set its benefits as far as social and economic areas are concerned. The utilization of a particular process depends on the quantities of available organic matter, local climatic conditions, time and money. These virtues make composting an ideal option for processing the enormous quantities of biodegradable solid wastes that are generated in the world.

Abstract: Ordinary portland cement (OPC) has been traditionally used as the binding agetn in concrete. However, it is also necessary to search for alternative low-emission binding agents for concrete to reduce the environmental impact caused by manufacturing of cement. Geopolymer, also known as inorganic polymer, is one such material that uses by -product material such as fly ash instead of cement. This report has investigated the suitability of using an existing consitutive model originally proposed by Popovics for Ordinary Portland cement concrete. It was found that the equation of Popovics can be used for Geopolymer concrete with minor modification to the expression for the curve fitting factor. The modified expression provided better correlation between the experimental and calculated stress-strain curves. The slightly modified set of stress-strain equations was then used in a non-linear analysis for reinforced concrete beams A good correlation is achieved between the predicted and measured ultimate loads, load-deflection curves for 16 test beams using sand and M-sand.

Abstract: A facultative alkaliphilic bacterium Bacillus flexus FPB17 (GenBank accession no. JN415115), isolated from sediment samples of an alkaline lake, was selected for the production of alkaline phosphatase. Maximum alkaline phosphatase productivity was obtained by using ribose as a carbon source and peptone and meat extract as a nitrogen source in a C:N ratio of 2:1. Alkaline phosphatase production was optimum at pH 9, temperature 350C and NaCl concentration 0.5 g%. The presence of different inorganic and organic phosphate sources (concentration above 0.5 mM) in the medium repressed the enzyme production. Deviations from optimum fermentation parameters drastically disturbed the enzyme production. The alkaline phosphatase productivity was not growth associated and was found to be optimum under aerobic, mesophilic, alkaliphilic conditions. Acephate, teh organophosphorous insecticide was degraded by the strain FPB17 in alkaliphilic conditions which indicates the role of alkaline phosphatase enzyme in bioremediation of acephate.

Abstract: Sewage waste and its management is the rising problem in all the growing cities which may be due to increasing urbanization and industrialization. In the present study, isolation and enrichment of hydrolytic miroorgnisms was using sewage samples collected from three different locations i.e., Industrial, Residential and Institutional sites of Gwalior city. Physico-chemical characteristics such as Total Dissolved Solids (TDS), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD), total microbial load were initially analyzed. The pH and DO levels were within the limits in all the three samples tested. However, BOD and COD levels were high indicating the pollution level in the samples. Total bacterial load varied from 35.83 x 104 CFU/mL in the three samples. Least load was recorded in industrial sample while it was high in residential zone. Thirty eight hydrolytic bacterial colonies were isolated by enrichment technique and characterized for their cellulase, amylase and protease enzyme producing activity. Among the 38 isolates, cellulose, amylase and protease enzyme producing colonies were 18.42%, 15.78% and 50%, respectively, while 15.78% colonies were noticed to be producing all the three types of enzymes. Analysis of growth pattern has shown that the application of selected isolates into autoclaved sewage samples has shown the steap increase in the hydrolysis of biopolymers more efficiently as compared to control. Thus application of strains isolation and enrichment of hydrolytic bacteria from same site into sewage may help for the degradation of complex biopolymers present in sewage water and efficiently manage sewage pollution in given complex environmental conditions.
